Brain Bumps uses cookies and similar technologies so the store can work, so we can understand what is useful, and — only if you allow it — so advertising can be measured. This page is the documentation for those technologies.

Needed for the shop to function: cart, checkout, account login, fraud prevention, currency/localization, and storing your cookie choice. These do not require consent.
Optional
Helps us see which pages are used and where the experience breaks. Shopify analytics and any analytics pixels you install load only after you allow this category.
Optional
Used to measure ads and, where allowed, to show relevant offers. Advertising pixels (Meta, Google, TikTok, and others you add in Shopify) wait for this category.
Optional
Remembers non-essential choices that personalize the visit, such as locale. The on-site accessibility widget uses local storage on your device and is not used for advertising.
Names and durations can vary slightly by browser, Shopify updates, and which apps or pixels are installed in this store. If we add a new optional tool, it stays off until you accept that category.
